Notes before you start

• Source: "Book Mark", Jewel Crochet Book: A Collection of Unique and Useful Designs with Full Working Instructions, Miller-Clark Designing Company, St. Joseph, Missouri, 1915. Public domain in the USA.
• As printed — materials: Not given. Gauge: Not given.
• Modernisation note: Stitches converted by the book's own printed stitch key (“Key to Terms Used in this Book”), not by name — this book uses the older British-style naming, so its names do not mean what the same names mean today. Chain (ch) = ch. Slip stitch (slst), hook through a stitch, draw a stitch through that and the loop on the hook without throwing thread over = sl st. “Double” (d), hook through the work, draw a stitch through making two on the hook, thread over and draw through both = modern single crochet (sc). “Half treble” (htr), thread over, hook through, draw a stitch through, thread over and draw through all three = modern half double crochet (hdc). “Treble” (tr), thread over, hook through, draw a stitch through making three on the hook, then work off two and two = modern double crochet (dc). “Double treble” (dtr), thread over twice and cast off three times, two and two and two = modern treble (tr). “Triple treble” (ttr), thread over three times and cast off four times = modern double treble (dtr). So every printed tr becomes dc here, every printed dtr becomes tr, and every printed ttr becomes dtr.
• Modernisation note: The book's shorthand is written out in modern US form: ch = ch, sl-st = sl st, d = sc, htr = hdc, tr = dc, dtr = tr, ttr = dtr, st(s) = st(s), R = Row or Round, j = join (with a slip stitch), bet = between, m (mesh) = the chain-1 space of the mesh ground, “miss” = sk, “thread over hook” = yo, “* all around” / “* from **” = rep from *. Ordinal row names (“1st R.”, “2nd R.”) are written Row 1, Row 2, or Round 1, Round 2 where the piece is worked in the round; where the book calls a circuit of a circular piece a “row”, the round reading is given in the heading and the change is noted.
• Modernisation note: The book prints each design as one unbroken paragraph; it is split here into one row, round or step per line, with stitch order and counts unchanged. Section headings in bold in the book (Rose, Seed Pods, Crown, Edge, and so on) are kept; any other heading is added for navigation and named as added.
• Modernisation note: Check: no thread size and no hook size are printed for this design. The thread and hook in the modern materials are a starting suggestion read from the scale of the photograph and from the sizes the book prints for its other designs; they are not from the book.
• Modernisation note: Thread is printed only as a number (“No. 60 thread”, “No. 20 thread”) with no brand and no yardage anywhere in the book. The modern equivalents given are approximations only: a size 60 or size 20 mercerized cotton crochet thread of the same size number. No yardage is printed for any design in this book, so none is given here.
• Modernisation note: Hooks are printed only as steel hook numbers (No. 9, No. 10, No. 11) with no diameters, so no exact metric size can be read from the book. The metric sizes given are approximate starting points read across to the modern US steel-hook scale, on which a higher number is finer; work a swatch and change hook size to match any printed measurement.
• Modernisation note: No stitch gauge is printed for any design in this book; work a swatch and match any printed measurement before starting.
• Modernisation note: The printed page is the authority for this transcription; every row was read from the page image, because the scanned text of this book is unusually broken. Where a digit could genuinely be read two ways it is flagged in a Check note below rather than guessed at.
• Modernisation note: The book's “shell” is defined in Row 2 as (2 dc, ch 2, 2 dc) worked under the chain-2 of the shell below, and is written “shell” after that, as printed.
• Modernisation note: Check: Row 7 is printed as “like first R.”, though Row 1 begins on a foundation chain. Read it as the block-and-mesh arrangement of Row 1 worked over the previous row, not as a new chain.
• Modernisation note: Check: the length of fringe and how many strands to a tassel are not printed; cut the fringe to suit the marker.
• Modernisation note: Check: the colour is not printed; the marker photographs as white.
• Modernisation note: Finishing line (fastening off and weaving in ends) added; the fringe line is the book's own.
• Modernisation note: Metric conversions added.
